German term (edited): angels�chsisch (politically speaking)

I am quite surprised that "anglo-amerikanisch" is not the source term you are working from, since "angelsächisch" also has a narrow ethnic connotation in German and is largely limited in proper use to one of the tribes which originally inhabited the British Isles.
In a political context, one speaks either of British or American foreign policy, hegemony etc. or, more often in more abstract analyses, of e.g. "Anglo-American" neoliberalism (which incidentally also includes Canadians, Australians and New Zealanders, even though their contributions to international politics usually carry much less weight).

Al-Qaida and anthrax have both now been discarded as too fragile reeds to sustain the projected attack on the evil axis. Instead, we are back to "weapons of mass destruction". This has served as the rationale for the Anglo-American bombing of Iraq, carried on almost continuously now for more than three years. Never mind that years of intensive UN inspections found no evidence of an Iraqi capacity to produce and deliver such weapons, whatever its intentions. Scott Ritter, ex-deputy head of the UN inspectors, has declared Iraq "effectively disarmed".

The distinctive legal tradition is the key to understanding the need for this distinction in language usage. The Anglo-Saxon tradition of case law or legal precedent, as opposed to codified law, along with the Protestant Christian influence in the law-making process is at least implicitly responsible to a large degree for the idiosyncracies of the British and American political traditions. It is clear that after 15 centuries of evolution, Anglo-American thinking only faintly resembles whatever social historians would have us believe may have constituted the original \"Anglo-Saxon\" mentality.
